Multi-material golf club head

ABSTRACT

The presently disclosed technology is directed to a golf club head. For example, the golf club head may include a body that includes an upper hosel region. The golf club head may include an upper hosel component to engage the upper hosel region.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a Continuation-In-Part (CIP) of U.S. patent application Ser. No. 18/092,733, which is a CIP of U.S. patent application Ser. No. 17/725,075, filed on Apr. 20, 2022, the disclosures of which are incorporated by reference in their entirety.

FIELD OF THE INVENTION

The present invention relates generally to a multi-material golf club head wherein the junction between the two different components made from different materials are seamlessly incorporated within existing visual cues of a golf club head to provide an aesthetically pleasing joint between the two components. More specifically, the present invention relates to identifying the existing visual cues of a golf club head together with the different bonding needs of the golf club head at the desirable visual cue, and continuously adjusting the design of the joint between the two different components depending on the needs of the golf club head at across the entire junction between the two different components.

BACKGROUND OF THE INVENTION

Utilizing multiple materials to design a golf club head has been around for a long time. U.S. Pat. No. 3,985,363 to Jepson et al. illustrates one of the earliest attempts to utilize multiple materials to improve the performance of a golf club head via the utilization of wood, metal, and plastic.

Despite all of the advantages associated with the utilization of material, two of the biggest drawbacks associated with multi-material golf club head are 1) the difficulties in securely joining materials to withstand the impact forces with a golf ball, and 2) preserving the aesthetics of the golf club to minimize the distractions associated with the differing visuals of the different material.

U.S. Pat. No. 5,385,348 to Wargo illustrates one of the earliest examples of utilizing threaded fasteners to secure a heavy secondary golf club component to the main chassis of the golf club head. U.S. Pat. No. 5,385,348 to Wargo utilizes replaceable inserts that have their weights and characteristics varied by controlling the amount and location of a layer of weightly material attached thereto.

U.S. Pat. No. 7,037,214 to Nakahara et al. illustrates the utilization of a lightweight material to replace the crown portion of a golf club via flanges wherein the ratio of the specific gravities is equal to or superior to 1.3. The bond between a thin crown piece and the chassis of the golf club head creates a unique set of challenges, as lightweight materials tend not to bond well to metallic materials, and the bond usually creates a visual delineation that is undesirable visually.

Hence, based on the above, it can be seen that there is a need in the art for a multi-material golf club head that not only is capable of achieving a secure bond between the different components, there is a need to do it in an aesthetically pleasing way.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description describes the best currently contemplated modes of carrying out the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

Various inventive features are described below, and each can be used independently of one another or in combination with other features. However, any single inventive feature may not address any or all of the problems discussed above or may only address one of the problems discussed above. Further, one or more of the problems discussed above may not be fully addressed by any of the features described below.

FIG. 1 of the accompanying drawings shows a perspective view of a golf club head 100 in accordance with an exemplary embodiment of the present invention. The golf club head 100 if further separated into a body portion 102 and a crown portion 110. The body portion 102 further comprises of sub-components such as the striking face 104, a hosel 106, and a portion of the sole 108. The crown portion 110, in accordance with the current embodiment, includes a crown 111 and wraps around a skirt 112 of the golf club head 100 to form at least a portion of the sole 108.

The body portion 102 of the golf club head 100 in accordance with the present invention may roughly be 4.5 g/cc, as modern day driver type golf club heads are generally made out of a titanium type material; however, numerous other material may be used to form the body portion 102 of the golf club head without departing from the scope and content of the present invention so long as it can provide the structural rigidity of the golf club head 100. The crown portion 110 of the golf club head 100, at least in accordance with the present invention, may generally be made out of a lightweight material such as a fiber reinforced plastic type material with a density of less than about 2.0 g/cc, more preferably less than about 1.8 g/cc, and most preferably less than about 1.7 g/cc; however numerous other types of lightweight material may be used without departing from the scope and content of the present invention as long as it has a density that is less than that of the material used to form the body portion 102.

One key feature shown in FIG. 1 that is worth highlighting is the parting line 114 between the body portion 102 and the crown portion 110. It should be noted that visually, the parting line 114 is located significantly forward on the crown 111 ledge than any other prior art golf club head 100 incorporating multiple materials, as it follows the visual cue of a golf club head 100 that creates a natural break between the striking face portion 104 and the crown 111. Having this crown parting line 114 being located so far forward is beneficial to the performance of a golf club head in that it eliminates the undesirable visuals generally associated with multi-material golf club head wherein the crown portion 110 is made from a lightweight composite type material. However, having the parting line 114 between the crown portion 110 and the body portion 102 this far forward in the crown portion of the golf club head 100 comes with additional design challenges that will be discussed below.

FIG. 2 of the accompanying drawings shows a frontal view of a golf club head 200 in accordance with an exemplary embodiment of the present invention. The frontal view of this golf club head 200 shows the body portion 202 forming a portion of the sole 208 and the crown portion 210 forming a crown 211 and a skirt 212 of the golf club head 200. In addition to the above, this frontal view also allows the parting line 214 to be shown more clearly, once again illustrating that the location of the parting line 214 that separates the crown portion 210 from the sole portion 202 follows the contour of the upper edge of the striking face 204 in the striking face plane, and transitions towards to a line that is underneath the skirt 212 of the golf club head. Finally, this frontal view of the golf club head 200 shown in FIG. 2 also illustrates a cross-sectional line A-A′, to which a subsequent cross-sectional view figure can be provided to illustrate the bond between the crown portion 210 and the body portion 202.

FIG. 3 of the accompanying drawing shows a heel side view of a golf club head 300 in accordance with an embodiment of the present invention. In this view, we can once again see the main components of the crown portion 310 further comprising the crown 311 of the golf club head 300 and the body portion 302 further comprising a sole 308 of the golf club head 300. In this heel side view of the golf club head 300 shown in FIG. 3 , it can be seen that the parting line 314 falls below the skirt 312 of the golf club head 300 to form a portion of the sole 308. The parting line 214 (shown in FIG. 2 ), in the frontal view shown in FIG. 2 follows the natural visual cue of the topline of the striking face 204 (shown in FIG. 2 ), but in the side view shown here in FIG. 3 , it actually follows the natural cues derived from the sole 308 graphics as it wraps around the skirt 312 of the golf club head 300 into the sole 308.

Although the details of the bond between the crown portion 310 and the body portion 302 is not shown here in FIG. 3 and will be discussed in more detail in the subsequent cross-sectional views, it is worth noting there that the bond is generally achieved via a lap joint type of joint, wherein there is a beginning of an overlap and an end of an overlap. This key concept will be used to help define distance D1 below, as distance D1 is critical to the present invention in providing the improved aesthetic performance of the present invention.

In addition to the above FIG. 3 of the accompanying drawings also shows another key feature of the present invention by illustrating the forwardmost vertical plane 320. The forwardmost vertical plane 320 is a plane that is created in the x-y plane as illustrated by the coordinate system 301 that abuts the forwardmost portion of the golf club head 300. Often in a conventional golf club head 300 geometry, the forwardmost plane 320 abuts the leading edge of the face sole junction; however, in alternative embodiments of the present invention, the forwardmost plane 320 could abut any other location in the golf club head 300 without departing from the scope and content of the present invention so long as it fits the definition above.

Once the forwardmost vertical plane 320 is established, another very important distance D1 could be illustrated. Distance D1, as defined in the present invention, relates to the distance between the forwardmost vertical plane 320 and the forwardmost point 322 of said crown portion 310. In the current embodiment of the present invention, distance D1 may generally be less than about 17.5 mm, more preferably less than about 16.5 mm, and most preferably less than about 15.5 mm. This distance D1, as previously mentioned, is critical to the proper function of the present invention as it allows the parting line 314 between the crown portion 310 and the body portion 302 to be shifted to an existing visual cue that already exists in a golf club head 300 such as the crown topline transition. The ability to strategically place the parting line 314 of the different components of a multi-material golf club head 300 at a location that fits with an existing visual cue of a golf club head 300 is beneficial to the performance of a golf club head 300 in that it minimizes visual distractions of a golf club head that can often be undesirable.

Before moving on to a discussion about the undesirable visual generally associated with a prior art multi-material golf club head 500 (shown in FIG. 5 ), FIG. 4 of the accompanying drawings merely shows a toe side view of a golf club head 400 in accordance with an embodiment of the present invention, allowing the parting line 414 between the crown portion 410 and the body portion 402 to be shown more clearly. Although the parting line 414 shown in FIG. 4 mostly mirrors the parting line 314 (shown in FIG. 3 ) due to the fact that the sole 408 is symmetrical in terms of its graphics, the hosel portion of the parting line 414 is slightly different as shown in FIG. 3 due to the fact that only one side of a golf club head 400 has a hosel.

FIG. 5 of the accompanying drawings shows a top view of a prior art golf club head 500 where no effort is made to strategically align the parting line 514 between the crown portion 510 with the body portion 502 with any existing visual cue or natural feature of the golf club head 500. As it can be seen in FIG. 5 , the resultant golf club head 500 leaves a strange line across the crown of the golf club head 500, creating an undesirable and distracting effect that will be distracting to a golfer.

Comparing the top view of the prior art golf club head 500 shown in FIG. 5 with the top view of the current inventive golf club head 600 shown in FIG. 6 , golf club head 600 provides an improved performance in the visuals of the golf club head 600 by shifting the parting line 614 to the frontal crown transition portion defined as the forwardmost point of said crown portion 610 in FIG. 6 . It is worth noting here that despite the best efforts to create a seamless parting line 614 that matches with an existing visual cue of a golf club head 600, the parting line 614 does become more visually recognizable around the hosel 606 of the golf club head 600; as that region of the golf club head 600 does not contain any discernable visual cues that lend itself well to conceal the parting line 614. In addition to showing the improvement in the aesthetics of the golf club head 600 compared to prior art golf club head 500 (shown in FIG. 5 ), FIG. 6 of the accompanying drawings once again shows the distance D1, being measured from the forwardmost portion of the golf club head 600 to the forwardmost point 622 of the crown portion, along the z-axis.

FIG. 7 of the accompanying drawings shows a bottom sole view of a golf club head 700 in accordance with an embodiment of the present invention. In this sole view of the golf club head 700 we can see that the parting line 714 follows the visual cues of the sole graphics, allowing the golf club head 700 to create a visually seamless blend between the crown portion 710 and the body portion 702. In addition to the above, this bottom sole view of the golf club head 700 illustrates how the crown portion 710 wraps around a skit of the golf club head 700 to form at least a portion of the sole of the golf club head 700.

FIG. 8 of the accompanying drawings shows an exploded view of a golf club head 800 in accordance with an embodiment of the present invention. In this exploded view of the golf club head 800 shown in FIG. 8 , one can clearly how the crown portion 810 and the body portion 802 fit together via a lap joint as previously discussed. Although the cross-sectional view of the golf club head will provide even more detail below, the body portion 802 has a recess 823 around the perimeter of the body portion 802. The recess 823, shown in FIG. 8 is generally created to accommodate the thickness of the crown portion 810 at the various portions around the perimeter of the body portion 802, allowing the two components to bond together via a lap joint type of bond. However, in alternative embodiments of the present invention, other types of bonds such as a butt joint, a dado joint, a rabbet joint, a dovetail joint, a tongue and groove joint, or any other types of joint could be used so long as it is capable of joining the crown portion 810 to the body portion 802 all without departing from the scope and content of the present invention.

The exploded view of the golf club head 800 shown in FIG. 8 also illustrates another critical feature of the present invention, wherein the distance of the overlap between the crown portion 810 with the body portion 802 to form said recess 823 varies across different portions of the golf club head 800 depending on the unique bonding requirements at each location. Because the present invention shifts the location of the parting line around various parts of the golf club head 800 to accommodate for visual cues inherent within a golf club head 800, the bond strength required at the various portions of the golf club head 800 may be different, requiring different amount of overlap. This amount of overlap, generally quantified as the length of a recess 823 is generally defined as the distance between the beginning of an overlap to the end of an overlap. For the frontal crown joint recess 823 length, that length is defined as the difference between the forwardmost point 822 of the crown portion 810 and the rearward most point 824 of the recess 823 at the frontal body portion 802. For the aft rear joint recess length, that length is defined as the difference between the rearwardmost point 828 of the crown portion 810 and the forwardmost point 826 of the recess 823 at the rear of the body portion 802.

In order to illustrate this very important concept of creating and defining a recess 823 via the overlap, a cross-sectional view of the golf club head 900 is shown in FIG. 9 . This cross-sectional view of the golf club head 900 shown in FIG. 9 is taken along cross-sectional line A-A′ shown in FIG. 2 , down the center of the golf club head. In this cross-sectional view of the golf club head 900 the crown portion 910 is attached to the body portion 902 via overlapping lap joints created by recesses in the body portion 902. Circular region A and circular region B are also highlighted in FIG. 9 , allowing enlarged views of the crown leading edge recess and the aft portion recess to be shown in more detail in FIGS. 10 and 11 respectively, illustrating the different designs used to achieve the different bonds at different portions of the golf club head 900.

FIG. 10 of the accompanying drawings shows an enlarged cross-sectional view of circular region A shown in FIG. 9 , which reflects an enlarged cross-sectional view of a frontal crown junction point between the crown portion 1010 and the body portion 1002. Although it's been discussed briefly in earlier discussions, the bond between the crown portion 1010 and the body portion 1002 is generally achieved via an overlapping lap joint type of bond, with the body portion 1002 forming a frontal crown recess 1023 a to receive the crown portion 1010. The thickness of the frontal crown recess 1023 a in accordance with the present invention may generally be less than about 1.0 mm, more preferably less than about 0.9 mm, and most preferably less than about 0.8 mm, as crown portion 1010 is typically made from a thin lightweight composite type material. This thickness of the frontal crown recess 1023 a may generally be thicker than the actual thickness of the crown portion 1010 itself, because not only does it need to accommodate the thickness of the crown portion 1010 in the range of less than about 0.8 mm, more preferably less than about 0.7 mm, and most preferably less than about 0.65 mm, it also has to accommodate approximately 0.15 mm of glue bond thickness that is not shown in FIG. 10 . In this enlarged view shown in FIG. 10 , because the bond between the crown portion 1010 and the body portion 1002 at the crown leading edge is so close to the striking face plane, it has an increased overlap length to accommodate for the increased stress occurring at that portion of the golf club head. This overlap length D2, although may look like a linear length in FIG. 10 , is actually an arc length, but only appears linear due to the large radius of curvature at this portion of the golf club head. The increased overlap length at the crown transition, defined here as frontal crown transition overlap length D2, may generally be greater than about 12 mm and less than about 25 mm, more preferably greater than about 13 mm and less than about 24 mm, and most preferably greater than about 14 mm and less than about 23 mm. The frontal crown transition overlap length D2, as described in the present invention, may generally start at the forwardmost point 1022 of the crown portion 1010 and end at the rearwardmost point 1024 of the frontal crown recess 1023 a at the front of the body portion 1002.

FIG. 11 of the accompanying drawings shows an enlarged cross-sectional view of circular region B shown in FIG. 9 , which reflects an enlarged cross-sectional view of a rear sole junction point between the crown portion 1110 and the body portion 1102. Although this geometry may look more complicated at the rear portion of the golf club head due to the adjacent weighting member, the overall concept of the bond here remains the same with an overlapping lap joint created via a rear sole recess 1123 b in rear of the body portion 1102. Similar to the discussion above, the thickness of the rear sole recess 1123 b, because it is adapted to receive the same crown portion 1110, is generally less than about 1.0 mm, more preferably less than about 0.9 mm, and most preferably less than about 0.8 mm. However, in this rear portion of the golf club head, because of the rear edge is not subjected to as much impact stresses at the crown leading edge, the overlap length does not need to be as lengthy. The rear overlap length D3, in accordance with the current embodiment of the present invention, may generally be less than about 6.5 mm, more preferably less than about 6 mm, and most preferably less than about 5 mm. The rear overlap length D3, as described in the present invention, may generally be the difference between the rearwardmost point 1128 of the crown portion 1110 and the forwardmost point 1126 of the rear sole recess 1123 b at the rear of the body portion 1102 taken along the arc, and not just linearly.

In view of the dramatic difference in the crown transition overlap length D2 and the rear overlap length D3, it can be said that the present golf club head has a Ratio of Front to Rear Overlap Length of about greater than about 2.0, more preferably greater than about 2.5, and most preferably greater than about 3.0. The Ratio of Front to Rear Overlap Length defined by Equation (1) below:

$\begin{matrix} {{{Ratio}{of}{Front}{to}{Rear}{Overlap}{Length}} = \frac{{Crown}{transition}{overlap}{length}D2}{{Rear}{overlap}{length}D3}} & {{Eq}.(1)} \end{matrix}$

FIG. 12 of the accompanying drawings shows a cross-sectional view of the golf club head 1200 in accordance with an exemplary embodiment of the present invention. In this cross-sectional view of the golf club head 1200 shown in FIG. 12 , we can see that the distance of the hosel portion recess 1223 c between the crown portion 1210 and the body portion 1202 has an hosel overlap length D4 of greater than about 8 mm, more preferably greater than about 9 mm, and most preferably greater than about 10 mm. This length D4 is shown to be taken at an angle of 45° offset from the hosel axis, but could be measured from any angle that is between 15° to about 75° all without departing from the scope and content of the present invention. Moreover, the measurement of length D4 above is generally a measurement of the arc length as previously mentioned, despite it looking like a linear measurement in FIG. 12 . Finally, similar to the discussion above, a separate ratio of Hosel to Rear Overlap Length may be established by Equation (2) below, defining the relationship between the two components.

$\begin{matrix} {{{Ratio}{of}{Hosel}{to}{Rear}{Overlap}{Length}} = \frac{{Hosel}{transition}{overlap}{length}D4}{{Rear}{overlap}{length}D3}} & {{Eq}.(2)} \end{matrix}$

The Hosel to Rear Overlap Ratio Length, in accordance with the present invention, may generally be greater than about 1.0, more preferably greater than about 1.5, and most preferably greater than about 2.0

FIG. 13 of the accompanying drawings shows an exploded perspective view of a golf club head 1300 in accordance with a further alternative embodiment of the present invention. In this alternative embodiment of the present invention shown in FIG. 13 , we can see that the golf club head 1300 is still comprised out of two main components, the body portion 1302 and the crown portion 1310 similar to previous discussions. However, in this alternative embodiment of the present invention, the metallic body portion 1302 is now formed out of three components, a main body chassis 1332, an upper hosel component 1306 and a lower hosel component 1338. The main body chassis 1332 may have an upper hosel opening 1305 and a lower hosel opening 1337, adapted to engage the upper hosel component 1306 and the lower hosel component 1338 respectively. The upper hosel component 1306 and the lower hosel component 1338 are generally formed independently and separately from the main body chassis 1332 and could even be formed out of different material to achieve different properties in the golf club head 1300 all without departing from the scope and content of the present invention.

The upper hosel component 1306 shown in this embodiment of the present invention may generally be made out of a lightweight polymer such as Kyronmax® S-2212 type of material from Mitsubishi Chemicals for it's lightweight and high strength properties. However, in alternative embodiments, the upper hosel component may also be made out of stainless steel, aluminum, titanium, or even theoretically tungsten all without departing from the scope and content of the present invention. Making the upper hosel component 1306 separately from the main body chassis 1332 reduces the machining needs to be done directly to the main body chassis 1332 and streamlines the manufacturing of this upper hosel component 1306.

The lower hosel component 1338 show in this embodiment of the present invention may generally be made out of stainless steel material for its ability to lower and move forward the center of gravity, which is often a desirable location for the center of gravity of a golf club head 1300. However, in alternative embodiments of the present invention, the lower hosel component 1338 may also be made out of aluminum, titanium, tungsten, or even the lightweight Kyronmax® S-2212 material mentioned above should it be helpful in achieving the desired CG location. Similar to the upper hosel component 1306 discussed above, making the lower hosel component 1338 separately also reduces the machining needs that needs to be done directly to the main body chassis 1332 and streamlines the manufacturing of the lower hosel component 1338 as well.

In addition to the benefit in manufacturing indicated above by removing the upper hosel component 1306 and the lower hosel component 1338 from the main body chassis 1332 to be formed out of the same component irrespective of the desired loft or dexterity of the golf club head, and only the crown portion 1310 and/or the upper hosel component 1306 and/or the lower hosel component 1338 needs to be changed to accomplish the variety of golf club heads throughout the entire line. In addition to the above, in an even further alternative embodiment, the upper hosel component 1306 and the lower hosel component 1338 could even engage differing main body chassis 1332 having different lofts to expand the applicability of these sub-components to different club heads all without departing from the scope and content of the present invention. Finally, more detail regarding golf club heads 1300 having multiple components such as upper hosel component 1306 and lower hosel component 1338 could be found in U.S. patent application Ser. No. 18/075,642, filed on Dec. 6, 2022, the disclosure of which is incorporated by reference in its entirety.

FIG. 14 illustrates a cross-sectional side view of a golf club head 1400 in accordance with one or more embodiments of the presently disclosed technology. Current composite-aft body style constructions may have a limited amount of composite. In existing technology, in clubs composed of higher percentages of composite, the composite must be substantially thickened which lowers durability. Despite thickening the composite, the composite may weigh significantly less than a standard metallic golf club head, making it difficult to get golf club head 1400 up to a sufficient weight, whether determined by USGA, R&A, or other governing bodies or metrics. Golf club head 1400 may include body 1402, upper hosel component 1414, and upper hosel region 1420. Body 1402 may include body interior 1404, upper hosel opening 1405, body exterior 1406, first piece 1408, second piece 1410, and bonding component 1412. Body interior 1404 may include an interior surface of body 1402 and any internal volume of body 1402. Body exterior 1406 may include an exterior surface of body 1402.

Connection points between first piece 1408 and second piece 1410, as more clearly illustrated in FIG. 15 , which illustrates an exploded cross-sectional side view of a golf club head in accordance with one or more embodiments of the presently disclosed technology, may be perpendicular to a shaft axis as illustrated by right angles 1422. This may help secure first piece 1408 to second piece 1410 with an inserted shaft (not shown). The perpendicular connection points may help reinforce the bond between first piece 1408 and second piece 1410. For example, after a shaft (not shown) is inserted, the torque and/or tension used to hold the shaft to golf club head 1400 may help secure first piece 1408 to second piece 1410. In some embodiments, the angle of the connection points may be more or less than 90°. In embodiments, the disclosed configuration may provide additional composite material to be used in golf club head 1400.
